Ruger rifles come in a wide variety of guns from their manufacturer, Sturm, Ruger & Company, in the form of single-shot, bolt-action, semi-automatic and full-automatic rifles.
The Ruger No. 1 comes in nine varieties, with its barrels available in standard, heavyweight, and varmint barrels, as well as international style full-length forends and weather-resistant stainless steel. The action is strong, with a Farquharson-esque internal hammer falling block action and an underlever to cock the rifle. Because of the strength of the action, this rifle is good for fans of Wildcat cartridges.
The Ruger M77 Mark II comes in five varieties and over 20 calibers. Its design is based on the two-lugged bolt with claw extractor from the Mauser 98. One of the more unique features of the Ruger M77 is its angled action screw, which draws the action down and to the rear instead of down and to the stock like more typical front action screws.
The Ruger 77/22 comes in two varieties, the standard 77/22 and the 77/22 Hornet. The 77/22 has a 10-round rotary magazine, and is available with laminated, walnut, and synthetic stocks. The barrel is typically 20 inches ling, but can be 24 inches. The .22 Hornet is a popular choice for medium-range varminting.
The Ruger 10/22 is available in nine current and two discontinued varieties, with a removable ten or five round rotary magazine. The typical .22 LR wooden stocks can be anywhere from 16 1/8 to 20 inches long, while the standard Carbine version is 18 1/2 inches. Wooden stocks come in standard, deluxe, and international versions, and laminated wood or black synthetic stocks are also available. The 10/22, while considered an "adult gun," has such things as inexpensive ammunition, easy handling, and little recoil, which makes it ideal for shooters who are young or have little experience. It is popular with small-game shooters.
The Ruger Mini-14 is capable of firing both the .223 Remington cartridges and the 5.56x45mm military cartridge and is available in two varieties, the tactical and ranch rifles. They come in laminated, hardwood, or synthetic stocks and has an 18 1/2 inch barrel. With a design meant to have a mounted scope, they are excellent for small game hunting, when only a few quick shots are necessary.
The SR556 is a brand new form of Armalite model 15 rifle and uses piston operation. The barrel is 16 3/25 inches long and it currently only comes in one variety, though it is not legal to own in all states. Because of its piston, it is easier to maintain than gas-driven rifles, and runs cooler and cleaner as well.
As you can see, there are a wide range of options from which to choose when you're trying to select a Ruger rifle. If you keep your needs, skill level, and budget in mind as you make your decision, then knowing how to find the right Ruger for you should be a snap.
